Specifically, the second data line of n item D21、D22、……、D2nExtend and be spaced each other along column direction.Second data are driven
Dynamic device 222 includes along tactic n the second connecting node L2 of line direction1、L22、……、L2n；Wherein, i-th second companies
Meet node L2iWith i-th of first connecting node L1iIt is relatively corresponding, and i-th of second connecting node L2iConnect with i-th first
Meet node L1iIt is connected on the same terminal of drive system 40, so that the same terminal of drive system 40 provides identical signal
To i-th of second connecting node L2iWith i-th of first connecting node L1i.I-th the second data line D2i(1≤i≤n) is connected to
N-th-i+1 the second connecting node L2n-i+1.That is, first the second data line D21It is connected to n-th second connections section
Point L2n；The second data line of Article 2 D22It is connected to (n-1)th the second connecting node L2n-1；And so on；(n-1)th second number
According to line D2n-1It is connected to corresponding second the second connecting node L22；The second data line of nth D2nIt is connected to corresponding first
Second connecting node L21。
Further, referring to Fig. 4, second array substrate 22 further include: the direct-connected line Z of N item1、Z2、……、Zn；Wherein, i-th
The second data line of item D2iPass through i-th direct-connected line ZiIt is connected to the n-th-i+1 the second connecting node L2n-i+1.Here, described straight
Line is vertical with the second data line to be connect, but the present invention is not restricted to this.Further, it is preferable to ground, the direct-connected line Z of N item1、
Z2、……、ZnInsulation independently of one another, but the present invention is not restricted to this.In the present embodiment, the direct-connected line Z of N item1、Z2、……、Zn
It is all set in the same side of the second data driver 222, in Fig. 4, the direct-connected line Z of N item1、Z2、……、ZnIt is all set in the second number
According to the downside (being also possible to upside) of driver 222.
In addition, during actual fabrication, the direct-connected line Z of N item1、Z2、……、ZnInfall can carry out keeping away position by via hole
Connection, but the present invention is not restricted to this.For example, the direct-connected line Z of N item1、Z2、……、ZnNot in same layer, they each other by
Insulating layer separates, but i-th direct-connected line ZiIt is connected to i-th the second data line D2 of same layeriAnd the n-th-i+1 of same layer
A second connecting node L2n-i+1；Or bridge connection, such as direct-connected line Z are done at the intersection convergence of two adjacent direct-connected lines1
With direct-connected line Z2Intersecting has insulating layer, direct-connected line Z between converging1It is set under insulating layer, and direct-connected line Z2It is set to absolutely
On edge layer；But the present invention is not restricted to these connection types.
Since the first liquid crystal display panel 10 of double-side display device and the second liquid crystal display panel 20 show identical influence picture simultaneously
Face, then when the first data driver 122 provides data-signal to i-th the first data line D1iWhen, the second data driver 222
Identical data-signal is provided to i-th the second data line D2i.In this way, the image for showing the first liquid crystal display panel 10 and the
The image of two liquid crystal display panels 20 display is consistent, rather than left and right directions is reversed in 180 degree.
In conclusion control the first liquid crystal display panel and the second liquid crystal display panel using a drive system while showing identical
Image frame can simplify signal input apparatus and signal source quantity, and reduce the quantity of integrated circuit, thus reduce at
This, and it is conducive to the lightening development of double-side display device.
Although the present invention has shown and described referring to specific embodiment, it should be appreciated by those skilled in the art that:
In the case where not departing from the spirit and scope of the present invention being defined by the claims and their equivalents, can carry out herein form and
Various change in details.
